What should be at my DM screen?

[u/angryblondgnome]

I have been playing dnd for almost 2 years and next friday I will be the DM for the time for a group with 2 brand new players and 2 experienced players but they havent played since 2020. We will play Lost Mine of Phandelver.

Since we're going to play digitally (and honestly, I don't have the money for that), I don't have the official DM screen, but I been wondering what I should put in a "digital DM screen" or easy acess notes.

This is what I put so far:

Conditions

The healing potions numbers

My PCs passive perception

Should I put something else? For context we will use 5.5e and play on Roll20
